Article Description

We have studied the excess oxygen content and hole concentration in 110 °C annealed LaCuO prepared by electrochemical oxidation for 0<δ<0.12. Two distinct sites were observed with doping efficiency of 2 or 1.3 holes per excess oxygen atom. The occupation of the two different sites is determined by a critical carrier concentration P∼0.06. As a consequence, a sudden increase of chemical potential of doped holes at P is suggested. © 1996 The American Physical Society.
